Description
Technical Field
The invention relates to the technical field of metallurgical equipment, in particular to a fan-shaped section driven roller of a continuous casting machine with an independent cooling and multisection combined structure.
Background
The continuous casting roller is one equipment for bending, straightening, guiding and drawing casting blank, which is cooled and solidified once in a crystallizer of continuous casting machine to form thin blank shell and is solidified step by step in two cold areas, and is contacted with casting blank with temperature up to 900-1100 deg.c, and is heated and radiated by it, and is also acted by the action of casting blank bellying force and bending straightening force of casting blank caused by molten steel static pressure, so that its working condition is very bad, and the roller surface is easy to produce fatigue crack under the action of alternating thermal stress. Under the conditions of continuous casting production exchange tundish and blank stagnation, when the pulling speed of a casting machine is reduced to zero, most of cooling water in a secondary cooling zone is in a closed state, a continuous casting roller stops rotating and is in static contact with a high-temperature casting blank, the roller surface is easy to generate high-temperature oxidation under the action of a large amount of heat load, and the roller body is easy to generate bending deformation.
The existing continuous casting machine is used for reducing center segregation of the casting blank caused by bulging deformation in the casting blank solidification process, reducing surface cracks and internal cracks of the casting blank and improving the quality of the casting blank, and a fine-diameter and small-space close-packed continuous casting roller row design is generally adopted. Because the diameter of the continuous casting roller is thin, the strength and the rigidity are relatively low, bending deformation is easier to generate, and the breakage failure of the shaft head is easy to generate.
The continuous casting roll comprises a crystallizer foot roll, a bending section continuous casting roll and a fan-shaped section continuous casting roll; to maintain the strength and rigidity of the thin diameter continuous casting rolls, segmented roll designs are typically employed; in order to reduce the deformation of the roller body under the high-temperature working condition, the crystallizer foot roller and the bending section continuous casting roller adopt secondary cooling water to carry out external spray cooling on the roller surface, and the fan-shaped section continuous casting roller adopts machine cooling water to carry out internal cooling.
Fig. 1 shows a sector driven roller of a three-segment continuous casting machine designed and adopted by the SPCO company in japan, wherein the roller consists of a bearing 1', a bearing seat 2', a segmented roller body 3', a connecting water jacket 4', a water jacket seal 5 'and a rotary joint 6'. Cooling water enters the sectional roller body 3 'from the rotary joint 6' at one end, the cooling water is led into the other sectional roller body 3 'through the connecting water jacket 4' after cooling the sectional roller body 3', and finally is discharged from the rotary joint 6' at the other end. In the continuous casting machine driven roller with the structural form, due to the fact that the adjacent sectional roller bodies 3' have the difference in diameter due to unavoidable machining errors, under the condition of continuous casting machine multi-furnace continuous casting, relative rotation can occur between the sectional roller bodies 3', the water jacket seal 5' becomes dynamic seal, abrasion failure and leakage are easy to occur, and the leaked cooling water further causes premature damage after bearing lubrication failure.
Figure 2 shows a sector driven roller of a triple section caster of the type EcoStarSpiral developed by VAI corporation. The sectional roller sleeves 7 'are connected through a short shaft 8', a cooling water hole is formed in the center of the short shaft 8', and the short shaft 8' is connected with the roller sleeves through a large interference. After cooling water cools the sectional roll sleeves 7 'from one end rotary joint through the spiral water tank, the cooling water enters the other sectional roll sleeve 7' through a central cooling water hole of a short shaft 8 'connected between the sectional roll sleeves 7', and finally is discharged through the rotary joint at the other end. The driven roller of the continuous casting machine in the form is inconvenient to maintain and has higher maintenance cost because the middle connecting short shaft is required to be cut off after the bearing and the roller surface are maintained and replaced and the roller surface are worn.
Fig. 3 shows a fan-shaped section driven roller of a mandrel type three-section continuous casting machine designed and developed by VAI company, wherein the roller consists of a bearing 9', a bearing seat 10', a roller sleeve 11', a mandrel 12', a flat key 13 and a rotary joint 14 '. Cooling water enters the mandrel 12' from one end rotary joint 14', and cools the mandrel 12' and the roller sleeve 11' connected with the mandrel through interference and flat keys 13 '. Because the mandrel 12' is of an integral structure, cooling water is not easy to leak, but the interference joint surface between the roller sleeve 11' and the mandrel 12' is easy to be detached due to the engagement of the high temperature and the cooling water for a long time, so that the bearing is very inconvenient to replace and repair the roller sleeve.
